WINDOW-MIRROR.

SPECIFICATIQN forming part of Letters Patent No. 398,Q94,'dated March 5, 1889. Application tiled November 16, 1888. Serial No. 291,04() (No model.)

To @ZZ whom it may concern.-

Be it known that I, NIELS ANDERSEN, a citizen et the United States, residing at Decorah, in the county et finneshiek and State of Iowa, have invented a new and useful Improvement in Window Mirrors or Rei'lectors, ot which the following is a specification.'

ltyinvention relates to au improvement in window mirrors or reflectors; and it consists in certain novel lfeatures,hereinat ter described and claimed.

In the accompanying drawings, Figure l is a front View et a mirror embodying my invention. Fig. 2 is a vertical section on the line x r ot Fig. l. Fig. 3 is a plan view showing one ot' the supporting-arms in detail.

Referring to the drawings by leiter, A designates a bracket-arm having its lower end provided with transverse perforations B, through which securing-screws are passed into the window-iframe or other support to secure the device in its operative position. The upper end of the bracket-arm is provided with a ball, C, having a vertical opening, D, extending entirelp7 therethrough.

E designates the mirror-supporting arm, having the mirror F secured to its outer end and having its inner end provided with a hemispherieal bearing or cup, G, which rests upon the ball C atthe upper end of the bracketarm A, and is provided with a diametrieal slot, H,as shown.

I designates the pivotal fastening bolt,

which is in sorted vertically downward through the slot H in the cup G and the opening D in the ball C. The lower end of this belt depends below the said ball C, and is provided with a securing-nut, J, which is adapted to be turned upward upon said bolt, so as to iirnily clamp the several parts together.

As shown in the drawings, there are two mirrors supported by my device, each one having an arrn, E, provided with a cup, G,

one of said cups bearing against the under side of the ball and the other resting upon said ball. It will be readily understood, however, that the series or number of mirrors may be increased or diminished at will without eiieeting a departure Ytrom my invention.

The mirrors are designed more especially 5o for use on dwelling-houses where it is desired to witness what passes in the street. The mirrors are adjusted so that each mirror will deflect the images et" persons passing on the street, so that a person in the room, by look` ing through the window into the mirrors, may be informed ot all that transpires outside without being discovered, each mirror reflecting the scene at one end ot the street.

The mirrors can be quickly adjusted by loosening the securingnut on the pivotal bolt, so that the mirror-supporting arms can l be moved around upon the ball to give 'the mirrors the desired angle, the slot in the cup slipping upon the pivotal bolt, so as to allow said movement of the mirror-supporting arms. The mirrors can be also moved circular in a vertical plane, so as to reflect what goes on above and below. It will be seen that the said arms can be moved in any desire'd direction, so as to secure the proper adjustment of the mirror, land the said adj ustment can be quickly eltected.

The mirrors can be arranged at the corner of a building, so that one mirror will refleet what transpires in one street and the other mirror will reflect what happens in the intersecting street. The device is very siniple, and its advantages are thought to be obvious.

Having described my invention, what I claim, and desire to secure by Letters Patent,

l. 'The combination of the bracket-arm having a ball at its upper end, the mirror-supporting arm having a cup resting on said ball and having a diametrical slot, and the pivotal securing-bolt inserted vertically through said ball and the. slot in the cup, as set forth.

2. The combination ot the bracket-arm having a ball at its upper end, the mirror-supporting arm having a cup resting on said ball and provided with diametrieal slot, and the pivotal securing-bolt inserted through th e ball and the slot in the cup, as set forth.

3. As an irnpoveinent in window-1nirrors, the combination of the bracket-arm having a ball at its upper end provided with the vertical opening, the 1nirror-suppoi-ting arlnliav- In testimony that I claim the foregoing` as' presence of two Witnesses.
